Select all of the equations that will produce exponential decay.


multiple answers can be chosen.

Answer:

A.) The curves do not intersect.

Step-by-step explanation:

By looking at the graph, we can see that the curves do not intercept, meaning that the equation has no solutions.

First, here we have the graph of the lines:

Which can be seen at the end of the answer.

In the graph, you can see that the lines never do intercept, this means that the equation:

log₆(x - 1) =  log₂(2x + 2)

Has no solutions.

Answer:

22.5°

Step-by-step explanation:

First we need to figure out the size of the interior angles on the inside.

The formula of figuring out the total degrees of all the interior angles of any shape is (n-2)×180°.

N is the number of sides.

If we substitute our number of sides (8) we get this:

(8-2)×180°

6×180° = 1080°

Then we divide 1080 by 8 since this is a regular octagon (all angles are equal in a regular shape).

1080° ÷ 8 = 135°

Focusing on the triangle now, we now know that the angle on the tip of the triangle is 135° as it has not been split by the line.

Using the rule of angles in a triangle add up to 180°. We do this sum:

180° - 135° = 45°

There are 2 angles left in the triangle so we do:

45° ÷ 2 = 22.5°

Therefore the angle of x is 22.5°.

The equations of E and R are illustrations of cost and revenue functions

The equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p

The cost and the revenue functions are given as:

E = -20,000p + 90,000

R = -2,170p^2 + 87,000p

At the break even point, we have:

E = R

Substitute known values

-20,000p + 90,000 = -2,170p^2 + 87,000p

Hence, the equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p

Given:

A student has 6 nickel 14 dimes and 8 quarter.

To find:

The ratio of the total number of coins to the number of nickels.

Solution:

We have,

Number of nickels = 6

Number of dimes = 14

Number of quarter = 8

Total number of coins = 6+14+8

                                     = 28

Now, the ratio of the total number of coins to the number of nickels is

[tex]Ratio=\dfrac{\text{Total number of coins}}{\text{Number of nickels}}[/tex]

[tex]Ratio=\dfrac{28}{6}[/tex]

[tex]Ratio=\dfrac{14}{3}[/tex]

[tex]Ratio=14:3[/tex]

Therefore, the  ratio of the total number of coins to the number of nickels is 14:3.

C. The difference quotient is 10x+5h +6, so the average rate of change is 10(1)+ 5(4) + 6 = 36

Step-by-step explanation:

The statement is the difference quotient is 10x+5h +6.

It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

Given function:

g(x) = 5x² + 6x

interval is x= 1 to x=5

so, the average rate of change is

=10(1)+ 5(4) + 6

= 36

Answer:

26.67%

Step-by-step explanation:

In the Seventh grade Rachel read 15 books in the 8th grade she read 19 books what is the percent of change of books read

The formula for Percent change =

New value - Original value/Original value × 100

New value = 19 books

Original value = 15 books

= 19 - 15/15 × 100

= 4/15 × 100

= 26.67%

The percent change of book read= 26.67%

Answer:

Distance between the plane and the observer is 511.86 miles.

Step-by-step explanation:

From the figure attached,

A plane is flying at point A which is at 200 m height and observer is at point C.

Angle of elevation (∠ACB) of the plane from the observer is 23°.

Let the distance between the observer and the plane is x meters.

By applying sine ratio for angle C,

sin(∠C) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(23°) = [tex]\frac{200}{x}[/tex]

x = [tex]\frac{200}{\text{sin}(23)}[/tex]

x = 511.86 miles

Therefore, distance between the plane and the observer is 511.86 miles.

Answer:

$27.5

Step-by-step explanation:

Let

x = pound over weight limit

Airline 1 = 20 + 10x

Airline 2 = 5 + 30x

Equate the fees

20 + 10x = 5 + 30x

20 - 5 = 30x - 10x

15 = 20x

x = 15/20

x = 0.75 pounds

How large was each airline's fee?

Airline 1 = 20 + 10x

= 20 + 10(0.75)

= 20 + 7.5

= $27.5

Airline 2 = 5 + 30x

= 5 + 30(0.75)

= 5 + 22.5

= $27.5

Answer:

$567.07

Step-by-step explanation:

Given that :

Purchase price = $200,000

Number of years = 30

Rate = 5.875%

Down payment = 10%

Hence, mortgage amount :

Purchase price - down payment

200,000 - (0.1 * 200000)

200,000 - 20,000

= $180,000

Using a mortgage calculator :

Mortgage amount = 180,000

Mortgage term = 30 years

Interest = 5.875%

Monthly payment will be : $1067.07

Hence, if she only wants to $500 from her own money, A rent of ($1067.07 - $500) = $567.07 will need to be charged
